Which approach feature is commonly associated with Category C aerodromes due to surrounding terrain?

• A. Curved or Offset Approach
• B. Direct straight-in approach
• C. ILS is mandatory for all operations
• D. Visual approaches only

Answer: (A)

When terrain around an aerodrome is challenging, especially for Category C airports, the approach path is often designed as a curved or offset final approach. This means the aircraft does not descend along a straight line directly on the runway centerline. Instead, the final approach course is offset or curved so the aircraft can remain clear of obstacles and terrain while still aligning with the runway in the final segment or after a controlled maneuver. This method keeps the flight path within obstacle clearance limits and conforms to instrument approach design standards, which is crucial when surrounding terrain would make a straight-in path unsafe. It allows pilots to descend and align with the runway safely without compromising clearance from terrain or obstacles. The other options don’t fit as well because a direct straight-in approach would require an unobstructed corridor that may not exist due to terrain, ILS being mandatory for all operations is not implied by terrain alone and many aerodromes operate with other precision approaches or non-precision approaches, and visual approaches only would not address obstacle clearance concerns in terrain-challenged environments.
